MECHANICAL SIGN.

Application filed September 1, 1923. Serial No. 660,572.

' plished through an air propeller.

The principal object of this invention is to produce a sign which will attract attention.

Another object is to produce a sign which will operate through the effect of a breeze contacting a propeller.

A still further object is to cause figures mounted upon the sign to move, for the purpose of simulating various mechanical operations.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of my device,

Figure 2 is a top plan view of Figure 1,

Figure 3 is a bottom plan view of Figure 1, with the housing removed,

Fi re 4 is a fragmentary cross section taken on the line 4-4 of Figure 1,

Figure 5 is a cross section taken on the line 55 of Figure 1,

Figure 6 is a modified form of my invention adapted to be attached to the radiator of an automobile, and

Figure 7 is a fragmentary detail view taken on the line 7-7 of Figure 6.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the

I numeral 5 designates a post which projects through a base 6 and terminates in a reduced portion 7 which is socketed in a lug 8 secured to a standard 9.

The base 6 has mounted on one end thereof a vane 11, while on the opposite end is mounted a bearing-block 12 within which is positioned a shaft 13 having a propeller 14' secured thereto. The opposite end of this shaft is mounted in a bearing-block 16 and has a disc 17 secured thereto. This disc 17 is adapted to abut a friction disc 18 mounted upon a crank shaft 19. The disc 17 is held in contact with the disc 18 through the medium of a spring 21 (see Fig. 1).

The crank shaft 19 has two off-set cranks 22 and 23 to which arms 24 and 26 of the 5 respective figures 27 and 28 are attached. These figures have their body portions pivoted as shown at 29 so that the body portions may rock as will be later described.

A pulley 31 is secured to the shaft 13 and has a belt 32 extending downwardly through a slot in the base 6 and over a pulley 33 mounted upon a shaft 34. This shaft is suitably journaled beneath the base 6 and is enclosed within the housing 36.

At 37 is shown a plurality of pins arranged upon the shaft 34 and adapted to successfully contact the end 38 of a lever 39,

fulcrumed at 41. This lever is adapted to have its free end contact the lower extremity 42 of a vertical rod 43. This rod has se cured thereto a disc 44 which contacts a spring 46 mounted between the disc and the base 6.

A. disc 47 is adapted to contact a spring 48 positioned upon the rod 43. The upper extremity of this spring 48 is in turn adapted to contact the under surface of a platform 49. Upon the upper end of this rod 43 is secured a figure, which figure has pivoted arms 52 and hinged legs 53, with the result that as the figure is violently moved up and down, these arms will simulate the arm movement of a dancing figure.

Referring again to the shaft 34, it will be noted that an eccentric is formed at 54, which eccentric is engaged by a yoke 56 formed upon a lever 57 fulcrumed at 58. The free end of this lever is connected to a rod 59 extending upwardly through the base 6. Surrounding this rod, at a point above the base, is a pump-like structure 61 having a handle 62 to which the arms 63 of a figure 64 are pivoted. This figure 64 is pivoted to legs 66 secured to the base 6.

By viewing Figure 3, it will be noted that a pin 67 is secured to the shaft 34 and adapted to engage the end 68 of a pivoted lever 69. The free end of this lever contacts the underside of a rod 71, which rod projects through the base 6 and has its upper extremity slidably positioned in the deck 72 of a drilling tower.

A figure 73 is pivoted to legs 74 and has In the modified form shown in Figure 6,

the propeller 77 rotates the shaft 78 which has a curved finger 7 9 secured thereto. This finger is adapted to contact a hinged plate 81 overlying which is a disc 82 having a rod 83 secured thereto. This rod extends upwardly through a platform 84: and has secured to its upper end a figure 86, Which figure is identical to the figures of Figure 1.

Vhen a device constructed in accordance with my invention is placed upon a suitable support,'the Wind will cause the rotation of the propeller "1% which will transmit motion through the friction discs 1? and 18 and cause the figures 27 and-28 to appear to be crankingjthe shaft 19, as though they wereuoperating ahoist. At the same time power will be transmitted through the belt 32 to the shaft 34, with the result that as the pins 37 contact the endof the lever-39 a bouncing motion will be given the vertical rod 43. This resultsin the figure 51 simulatinga dancing motion, and at the same time the eccentric 5e will cause an up and down motion of the rod, 59, withthe result that the figure 651- Will appear to be operating the pump 62. Simultaneously, the pin 57 Will engage the lever 69 and intermittently move the rod 71Iup and down, thus making the figure 7 3 appear to be drilling.

It Will thus be seen that Lhave constructed a device of this character which causes a plurality of figures to simulate various movements,-and one which will attract considerable attention.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim. I I

Havin'g thus described my invention, I claim:

In a device of the character described, a base, a shaft mounted above said base, means for rotating said shaft, alshaft mounted below said base androtatably connected to said first mentioned shaft, a crank mounted at right angles to said first, mentioned shaft, figures pivotally' secured to said crank, means fOlIll'iVlllg saidcrank from said first men- V tio'ned shaft, a plurality of pins mounted in said second mentioned shaft, a lever adapted to beengaged by said pins, a vertical rod adapted to be contacted by said lever, re-

silient means mounted on said rodforgiving a vibratory movement to said rod when said rod is reciprocated and a figure secured to said rod,'said figure having a plurality ofjointed parts. 7 y 1 In testimony whereof I afix my signature.
